Abstract

PURPOSE: To enlarge a measuring stroke and make it possible to measure inside dimensions, which are as small as possible, with a high precision by arranging a measuring spindle and a spare anvil on the same measuring axis and arranging a magnetic scale and a detection head in parallel with them and moving them in parallel.
CONSTITUTION: Measuring spindle 32 and spare anvil 33 are arranged on the same measuring axis, and bias is always given to measuring spindle by repulsive spring 34. Magnetic scale 35 and detection head 36 which are known conventionally are arranged in parallel in position separated from the measuring axis above in shield case 37, and the output of detection head 36 is taken out by lead wire 48. Then, guide rod 40 which is linked with measuring spindle 32 by linkage material 38 is screwed into linkage material 38 and bearing part 41 are arranged in parallel with the measuring axis, and measuring spindle 32 and magnetic scale 35 are moved according to the inside diameter of a measured object in parallel with guide rod 40, and the output is generated from detection head 36. Guide plate 42 is fitted rotatably around axis 43.
